Use regs[REG_SP_EL0] from register context instead of direct sp_el0 system
register read/write operations in arm64_syscall(). Replace read_sysreg(sp_el0)
with regs[REG_SP_EL0] and write_sysreg(usp, sp_el0) with direct assignment to
regs[REG_SP_EL0]. Ensures userspace stack pointer is correctly maintained from
register context during signal delivery, preventing userspace SP corruption on
syscall return.

Update the can_sendmsg() signature from "struct msghdr *msg" to
"const struct msghdr *msg" to match the updated sendmsg() prototype
and resolve compilation errors due to parameter type inconsistency.

To ensure consistency, in all places where the "sendmsg" function is used
either directly or indirectly, the type of the "struct msghdr *msg" parameter
needs to be modified to "const struct msghdr *msg".

We have added a defconfig configuration to set the page size of the flash.
According to the CFI protocol, the flash supports a single write operation
with a data volume ranging from byte size up to the maximum number of bytes.
However, the MTD device structure requires defining a page size, which serves
as the minimum write unit of the flash. Hence, this configuration is introduced.
Any page size within the range of 1 to the maximum number of bytes is considered
valid.

Convert g_mpu_region from single-CPU global variable to per-CPU array indexed
by this_cpu(). Change declaration from "unsigned int g_mpu_region" to
"unsigned int g_mpu_region[CONFIG_SMP_NCPUS]". Update all accesses in
mpu_allocregion(), mpu_freeregion(), and mpu_modify_region() to use
g_mpu_region[this_cpu()] for proper per-CPU MPU region tracking in multi-core

when we build with greenhills compiler, if the exception_common function
is put into a separate section: ".text.exception_common", then the
address of exception_common function is an even number, for example "0x16a6c",
in this case, it will trigger the UsageFaults:INVSTATE error.
The reason for this error is that in the GHS compiler, a section declared
through the ".section" directive must specify at least the "a" attribute.
Otherwise, this section will not be linked into the final file, and this
is why the address of exception_common function is invalid.
The following is the official explanation in the GHS compiler documentation:
"The reason for this error is that in the GHS compiler, a section
declared through the .section directive must specify at least the "a"
attribute. Otherwise, this section will not be linked into the final
file. The following is the official explanation in the documentation:
"Sections that are intended be part of the final linked output should
have at least the `a` attribute"
and for GHS compiler, the .text section is recommended specify the
attribute of `ax`.

The wdog callbacks are executed in the host's signal handler context, which has strict limitations on what operations can be safely performed. Specifically, signal handlers should not call non-async-signal-safe functions (e.g., sim_alsa use mutex_lock in wdog and cause deadlock).
This change only replaces uses of wdog for periodic tasks. Other interrupt callbacks that are still invoked from the host signal handler are not replace to work queue.
